To check your fan at the front of the van,first remove the lower grill.
Pull the wire off the sensor. Try to determin which of the three wires is
ground. Maybe brown? You can  jump a wire from the ground to one of the
other prongs.This could be the high or low speed. Do this from the
ground ,to the remaining prong,too.Fan should run on both speeds. If you
have a/c,try turning the a/c switch on. Even if your a/c is broken, the fan
should run. You can put your sensor in a bucket of boiling water and test
for continuity.Hot water will close the circut in the sensor. Try both
speeds here.

 Your shark swims too fast .You passed my vanagon store right up,in the
Washington dc area. Still, I have a fan with your name on it. Lot of hondas
to eat around here.
